staining a protein for live confocal microscopy

[Dominik79]

hi
I prepared a flagella protein from bacteria. I want to add this now to cells and view it under the microscope. The idea is now that the flagella maybe bind to a specific location on the cell.
However, to make this flagella protein viewable I have to stain it somehow with a (fluorescent) dye before I add it to the cells. How can I do that?

Other possibilities are to clone a gfp-expessing flagella, which I already tried unsuccessfully. Or with help of a primary and secondary antibody, which is quite expensive.

When I google I just find dyes for sds-gel stainings, like coomassie. Could this work for me as well?

thanks for reading this!
